A. BUTTLES SMITH, OF BROOKLYN, NEW YORK, ASSIGNOR TO WILLIAM B. RANKINE AND BENJAMIN W. FRANKLIN, BOTH OF SAME PLACE.

PR'lNTlNG- -TELEGRAPH.

SPECIFICATION forming part of Letters Patent No. $16,494:, dated April 28, 1885.

Application filed April 28, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, A. BUTTLES SMITH, a

citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Step-by-Step or Goldand-Stock Recording Instruments, of which the following is a specification. I My invention relates to the class of instruments known as printingtelegraphs, also called step-by-step or goldand-stock recording instruments, by which a record is made on a strip or fillet of paper.

In the drawings the same letters indicate the same parts in all the figures.

Figure 1 is a plan view, looking down upon Fig. 2 is a side view of the instrument, the point marked as in Fig. 1 being presented forwardly. Fig. 3 is a vertical sectional View on the line or x of Fig. 1.

A is the base of the machine. It may be made of any suitable material, and upon it the several devices are mounted.

B is an electro-magnet, which, on the passage of the current, attracts the armature B and its lever B, which is pivoted at B.

O is the retractile spring for the armature B, which for the sake of simplicity is prefer-, ably a plate-spring. The lower end of it is attached to the base A, preferably by a regulating-screw, O, by means of which the ten sion of the spring on the armature B may be regulated. The armature-lever B carries an anchor, D, at its forward end, which engages with the escapement'E, which is fastened upon a hub,E,which turns on aspindle, E, supported by the bracket E, which is fastened to the base A.

The relation of the anchor D and the teeth on the escapement-wheel E is'such that contact between either end of the anchor and the teeth of the escapement-Wheel effects forward revolution of the type-wheel to the extent of one type and locks the wheel, as hereinafter described. Thus the armature-lever B, at the end of both its forward and its retracted movement, revolves the type-wheel one type.

F is the type-wheel. It revolves horizontally, although it may revolve vertically or at any angle, the other devices being changed acpass through holes made in the wheel F, near its periphery, in which holes the little posts slide easily, being normally held up by the little springs F, the free ends of which are fastened to them and the other ends to some suitable part of the wheel F, or to the hub E, or to any other suitable point. On the lower ends of these little posts, and below the type wheel F, the typesi. 0., the letters, figures,

or other designations used for making-the de-.

sired record-are formed, and there may be more thana single letter or figure, if desired, on each post, and there may be as many of the little posts as desired, the size of the wheel F and the other parts of the apparatus being made to conform. These little posts should preferably be made of iron ease-hardened, for the sake of durability and to avoid magnetization. The types receive their ink from an ink-roller, T, located in the block H, or in any other desired manner.

G G are another pair of electromagnets placed in a second circuit, which on the passage of the current attract the armature G, which is supported on the end of a little sliding bar, G, which passes through ablock of metal, H, and projects from the front side thereof, terminating in a punch-button, H. A spiral spring, H, (seen in section in Fig. 3,) encircles the bar G, one end of which; takes against either theinner end of thepunchbutton H, or some other suitable shoulder on the bar, and the other end against a shoulder, 11, formed on the block H. This spring H is the retracting-spring for the armature G, and it also feeds the strip of paper when expanding.

I is a feeding-pawl. (Best seen in Fig. 3.) It is pivoted to the armature G, as seen at I,

and works through a recess, I, formed in the upper part of the block H. At its inner end it is curved upwardly, and terminates in fine sharp teeth-such as are usually used for the purpose of feeding paper or cloth in analo gous devices. At its rear end a spring, I, is fastened, the other end of which is attached of the pawl up'against the paper.

K is a stop-pawl, which is located within the recess 1 and in front of the feeding-pawl I. It is pivoted, as seen'atK, and has a spring pie d b n h i wh h u e the f ont end, i

which is furnished with sharp teeth the same as the pawl I, to constantly engage with the paper and prevent it from moving backwardly. which is supported on a spindle between the upper ends of the uprights L L, and passes downward over the magnets G and enters a slot, L, prepared for it between the upper surface of the block H and a thin metallic plate, L, which is fastened upon or is let into the block H. There is a hole, L, made in i this plate, coincident with the type the im- 1 pression from which is desired, through which the type strike and impress the paper, as hereinafter described. The slot is just wide and a thick enough for the paper to pass easily through it, and the pawls'l and K effect the feeding and holding of the paper by their pressure against it while held down by the plate L M M are another pair of electronagnets. They, when the current passes through them,

is pivoted to the bracket M.

above that one of the little posts F which it is desired to depress, for the purpose of making an impression of the type on its lower end, and preferably has a little hammer-like projection, N, on its end. It is retracted by the spring N, which may be attached at its upper end to an arm, N, and passes through a hole, N, in the bracket M, or in any other suitable manner. By thus placing this hammer-bearing lever over the type,inst,ead of beneath them, and striking down upon them,ihstead of up against them, I avail myself of the weigh't'of the lever and hammer in aid of the magnets which actuate them, thus securing a sharp quick blow on the type, which renders their impression more perfect, and I also make the operation of the magnets more prompt and free. i a The degree of movement of the armature.- lever B is determined by the anchor'D and escapement-wheel E; that of the armatnre lever M by the posts F in one direction and by the set-screw O in the other. "i

' The degree of movement of the armature G and its bar G may as well as in the other two cases be regulated in a variety of ways; but since the movement of these parts effects the feeding of the paper I prefer to regulate it by. shifting the magnets G. This I do by attaching them to the slide-bar P, which can be clamped in any desired position by means of the clamping-screw P and the block .P, attached to the clamping-screw through which. the bar P passes. There may be a ring of metal or other suitable substance, P provided The paper S comes from a roll, as usual, 1

beneath the bar 1?, down upon which .the bar 3? will be clamped. By means of these devices the magnets G can be fastened in a mo-' ment at any desired distance from the armature G. into a hole, Q, cut in the base A, and the studs QQ,,o n which they slide while being adjusted, steady and support them,- the studs resting on the top of thebase A.

The operation is as follows: An intermittent current, is caused to pass through the magnets B, which, acting through the armature B and lever B and the spring 0, causes the anchor D, acting through the esoapementwheel E, to rotate the type-wheel F by intermittent or step-by-step rotation. This rotation is, however, twice as rapid as that of such wh els in erdihe y h uhi nts f t i class wh n p at d byele t Q-ihe h teeaii ee already stated, the a hor eeie on the s apement-wheel at both its forward and backward movement hus the h el ree iveet e o a mp l a e ch make and b ak o th current through the magnets B.

' 2. Thecombination,inaprinting-telegraph,

of a type-wheel rotated by an escapement controlled by a magnet in an electric circuit, the type being loose in the wheel and capable of independent movement, and a second electric circuit in which are two electro-magnets, the armature of one of which at stated times causes the type one by one to move against the paper, and the armature of the other feeds the paper, substantially as and for the purposes set forth.

3. The combination of the armature G and bar G, provided with'a punch-button and retractile spring,and the feeding-pawls I and K,

and the slot L,whereby the paper may be fed through the block H prior to the operation of the machine, substantially as and for the purposes set forth.

4. Thecombination,in aprinting-telegraph, of an electric circuit in which is placed an electro-magnet, the armature whereof, acting through a lever, rotates and looks a type-wheel, and a second circuit in which there are placed two electro-magnets, one of which, operating through its armature andlever, feeds the paper to the instrument, and the other, operating through its armature and lever, causes the printing to be done, substantially as and for the purposes set forth.

5. In aprinting-telegraph, the combination of an armature which when attracted by its magnets sets the feeding mechanism, aretractile spring which both retracts the armature and feeds the paper, and magnets for the attraction of the armature, provided with means whereby they may be adjusted relative to the armature, substantially as and for the purposes set forth.

6. The combination,in a printing-telegraph, of the block H, the typewheel F, the typebearing posts F, the said block having the cutaway portion R, whereby the type may be readily removed and replaced, substantially as and for the purposes set forth.

7. The combinatiomin a printing-telegraph, of a horizontally-rotating type-wheel, paper passing below the type, and an inking device also placed below the type, so that the ink deposited upon the surface of the type will be retained thereon by gravity, and not tend to run down into the face or along the sides of the type, substantially as set forth.
